I partitioned and installed a 2nd copy of Vista on my hard drive and then deleted the original C: drive. Now I get a black screen with a blinking cursor when I boot the computer. I have used the "Repair Your Computer" thing with the Vista CD and done the command prompt stuff. I also installed a new copy of Vista to see if that would fix it, but I still get the black screen with the blinking cursor. I can tell that all of my files are still on my computer, but the computer does not have the information to boot anymore because that information was on the C drive. How do I fix that?
